Wesley's human-mumma Molly Moore works at a veterinary clinic which her dad Jim Moore owns, and both noticed something unusual about Wesley's mouth after losing his teeth. His mouth was unable to close as to new teeth growing in and he was basically in puppy teeth hell.

Speaking to Buzzfeed News, Molly said that because of the teeth issue Wesley was losing weight and wasn't playing with his toys.

"We needed to do something for him to be pain-free and live a happy puppy life."

We support this.

Wesley's human-grandfather Jim told Buzzfeed News that it is not for aesthetics, but for "pain or function."

"[People] think we did this so he won't get picked on in the playground, but there's a serious medical reason."

The viral photo of Wesley smiling with his braces got over 288,000 shares on Facebook and we can seriously see why...
